Has Turkey become a state sponsor of terrorism?

Jonathan Schanzer and Aykan Erdemir:

On Monday, four children of an American and his Israeli wife killed by the Palestinian terrorist group Hamas in 2015 filed suit against Turkey’s Kuveyt Turk Bank in a New York court. They charge that the bank helps Hamas finance its terrorist attacks, allegations the firm is almost certain to deny.

The lawsuit against this Shariah-compliant bank, which counts the Turkish government as a shareholder, comes two weeks after the US Treasury sanctioned 11 Turkey-linked entities and individuals for supporting Hamas and other jihadist outfits. The evidence keeps mounting: Turkey has become a haven for regional baddies.

Under President Recep Tayyip Erdogan, Turkey has become a permissive jurisdiction for rogue regimes and their illicit bankers. Between 2012 and 2015, Tehran relied on Turkish banks and a dual Iranian-Turkish gold trader to circumvent US sanctions at the height of Washington’s efforts to thwart the Islamic Republic’s nuclear ambitions. It was the biggest sanctions-evasions scheme in recent history.

Similarly, Venezuela's Maduro regime has been using Turkish-based companies in a money-laundering network involving the sale of Venezuelan gold. The US government sanctioned that network in July.

Reports suggest that a Treasury-sanctioned money man for the ­Assad regime in Syria owns an extensive network of companies in Turkey, thus enabling Syria to circumvent US sanctions.

Turkey has also proved a forgiving host to terrorists. In April, Treasury sanctioned six individuals and a Turkish money exchange for their role in bankrolling Islamic State. The action underscored how Islamic State terrorists continued to operate from Turkish territory well into 2018.

Turkish law enforcement is known to turn a blind eye to jihadists, while the country’s courts treat them leniently, often releasing them pending trial or granting them parole — in stark contrast to harsh treatment meted out to secular and pro-democracy dissidents.

After their ouster from Egypt in 2013, the Egyptian Muslim Brotherhood established new institutions in Turkey. In addition to Islamist propaganda, the movement’s television stations have broadcast death threats against Egyptian officials and foreign nationals in Egypt. Ironically, the Turkish government defends the Muslim Brotherhood’s “freedom of expression” even as Erdogan has silenced Turkey’s domestic opposition.

There is more.

I suspect that Turkey also helped to fund ISIS by buying the oil they had stolen.  I think they also hoped that ISIS would destroy the Syrian Kurds for them.   Erdogan is an Islamist extremists and should be treated as such.
